Welcome to Task 59's Winter Newsletter 
#HistoricNZEB

The International Energy Agency's IEA-SHC Task 59: Renovating Historic Buildings towards zero energy (HistoricNZEB) showcases examples of how historic buildings from across the world can be renovated to allow substantial reductions in energy use and associated carbon dioxide emissions, while safeguarding the buildings’ cultural significance.

We are looking for feedback on our Task 59 website, and its content. If you would like to give us some feedback about this, please email anne.schmidt@hes.scot.

This newsletter gives you an overview of the project’s latest case studies added to the HiBERATLAS platform, our new blog posts and publications, and updates on the project’s meetings and workshops.

On behalf of all the project’s partners and associates, we would like to thank you for subscribing!

Task 59 Final Conference

The registration for the SBE21 conference is now open! Visit https://sbe21heritage.eurac.edu/registration/ to register and for more information.

From the 14th to the 16th April 2021, the SBE21 Heritage Conference will bring together experts working in the fields of energy efficiency and historic building conservation to foster multidisciplinary dialogues and find new affordable and efficient retrofit approaches for historic buildings and municipalities. Scholars and practitioners worldwide have submitted a range of papers and are looking forward to sharing their contributions.

Considering the rapidly changing situation with regards to COVID-19, we announce that delegates affected by travel restrictions will be granted online access to the SBE21 Heritage conference.

SBE21 Heritage will take place as a hybrid virtual-physical event. We will do our best to make online experience as close as possible to in-person participation.

FEATURE HiBERATLAS Platform:

Latest Cases

 
The beta version of HiBERATLAS is continuing to grow. It includes 40 case studies, with more coming soon. Today we are presenting three of the new cases added to the website. Please continue to check back as new projects and features are added to the platform:
 

Klitgaarden, Hundested, Denmark

The building is located in Hundested, in the northern part of Zealand about seventy kilometres northwest of Copenhagen, Denmark. Klitgaarden is a free standing single-family house from 1875 in two stories with a total of 221 m2. The building is erected with solid masonry walls and a foundation of granite boulders on top of a stone foundation. The renovation project of the building aimed for a minimum heating requirement and a preservation of original outdoor facade details. It was finished in 2016. The renovation was motivated by a very high-energy demand for heating and in general the fact that the house had not been used in twenty years.
 

Single Family House, Gstaad, Switzerland

Every year in Switzerland more than 2,000 agricultural holdings are abandoned. The buildings often remain unused (CVP-Mo 11.3285). A redevelopment or conversion of older buildings into residential buildings is not always possible due to the federal legal restrictions on the preservation of cultural landscapes. It is questionable what a half- decayed building can do on a planet rendered uninhabitable by global warming due to development. Gabriela Matti proves that traditional buildings can easily be combined with the latest technology with the conversion of the unused Maiensäss in Gstaad. A comprehensive renovation transformed the unused and unheated wooden house into a modern PlusEnergyBuilding, that hasn't lost its "old charm."
 

Maison Rubens, Schaerbeek, Belgium


The “maison Rubens” is a typical middle-class row house from late 19th century, in neoclassical style. It reflects the Belgium bourgeoisie life at this period. House is organized in 3 zones: a main part including reception and living space (2/3) and secondary space for stairs, services and corridors (1/3). It has a heritage interest within its decorated front façade (balcony, ceramic tiles and blue stone) and the stucco ornamentation on the ceiling and cornicing at the top of the wall, as well as its marble mantelpiece. Since 1888 (date of construction) no major renovation had been done. The building was almost in its original condition, but in very bad conservation state. The renovation followed two main goals: i) very good insulation (using bio-based materials) and mechanical ventilation of the whole house while conserving the valuable heritage details. ii) energy consumption below 60 kWh/m²y.

Thermal performance of historical masonry structures: experimental data and numerical modelling


To promote more conscious reuse of historic buildings, it is necessary to deeply understand the thermal performance of historical built heritage, which is often characterized by masonry beam system. This study aims at assessing, through experimental measurements and numerical simulations, the thermal performance of the exterior walls for a building belonging to the historical heritage in Catania, Southern Italy. San Giuliano Palace, whose main front is reported in Figure 1, was built in the XVIII century as the residence of a very notable family, and currently hosts the administrative offices of the local University.

Embedding thermal comfort into retrofitting design


Reducing energy consumption in the built environment is one of the severest challenges of our times. This blog is arguing for the inclusion of thermal comfort into the retrofit design from the outset. Recognised as the prime objective of most construction, thermal comfort of occupants should be at the forefront of design decisions for retrofit ventures.
